IMPROVEMENT IN LASTING-JACKS FOR BOOTS AND SHOES.

Specification forming part of Letters Patent No. 209,986, dated November 19, 1878 application filed October 21, 1878.

To all whom it may concern:

Be it known that I, EDWIN J. E. RoLLINs, of Alton, of the county of Belknap and State of New Hampshire, have invented a new and useful Improvement in Shoemakers Jacks;

and do hereby declare the same to be described in the following specification and represented in the accompanying drawings, of which- Figure 1 is a side elevation, Fig. 2 a top view, Fig. 3 a rear end view, and Fig. 4 a longitudinal section, of a jack embodying my invention.

In carrying out my improvement I provide the jack with an auxiliary heel-rest, and hinge the main heel-rest thereto, so as to enable it to be turned laterally off or on such auxiliary rest, all being substantially as set forth. Furthermore, in connection therewith, I hinge the toe-rest to the body of the jack, and provide them with a lever-latch and a curved toothed rack or sector, such being to enable the toerest to be adjusted todift'erent positions relatively to either heel-rest.

The body of the jack at its middle is pivoted to a support-piece, which is hinged to the baseplate, and provided with a stop, the latter being to maintain the support-plate in position when raised into a right angle to the baseplate.

In the drawings, A denotes the body of the jack, B the support-plate thereof, andGthe pivotal screw-bolt connecting the two, such bolt having screwed 011 it a nut, D. The supportplate near its rear end is pivoted or hinged to the base-plate E, and when down closes into a recess, a, made therein to receive it. Such support-plate has a projection or lip, 1), arranged upon it, as shown, which, when the plate is in a vertical position, or about so, abuts against the base-plate and estops the support-plate thereon.

The rear end 0 of the body is what I term the auxiliary-last heel-rest, the main-last heelrest F, provided with the last-support pin, (1, being so hinged to the auxiliary rest orpart in which it is made as to enable it (the said main rest) to be turned down laterally, so as to uncover the auxiliary rest sufficiently to enable it to support a shoe-last when inverted and placed thereon, so that the toe part of the last may be on the toe-rest G. Such toe-rest G is also hinged to the rotary jack-body, and provided with a toothed sector, H, to receive a lever latch or pawl, I, which, hinged to the body, is provided with a spring, K, to press it (the said latch) into engagement with the sector, all being as represented.

The purpose of having the auxiliary-last heel-rest arranged and combined with the main-last heel-rest in manner as described is to facilitate the operations of applying an insole or an upper to a last.

In using the jack, the last is first inverted and placed on the toe-rest and the auxiliary heel-rest, the main heel-rest being previously turned down, so as to uncover the auxiliary rest. This having been done, the insole is next to be applied in the usual way to the last, after which the latter is to be raised and inserted within the upper. The main rest is next to be turned up, and the last is to be applied thereto and the toe-rest, or, in other words, should be jacked for the fixation of the upper to the insole. Thus by myimprove- Inent I save the usual jacking and unjacking the last forthe application of the insole to it preparatory to jacking it with the upper on it. Furthermore, by turning the main rest laterally relatively to the jack-body'when its support-piece is turned up, I am enabled to put the last into difierent or more convenient positions for trimming or finishing the sole or upper than could be accomplished were the main rest stationary relatively to the body. So, by having the toe-rest movable, as described, in respect to the body, and also having the body provided with the main heel-rest, hinged to the body, as set forth, the toe-rest can be adjusted to the last when inclined with the heel-rest.

That I claim as my invention is as follows, V12:

1.. The shoe-jack body as provided with the auxiliary-last heel-rest c, and with the mainlast heel-rest arranged therewith and hinged thereto, substantially as specified.

2. The shoe-jack body as provided with the main and auxiliary last heel-rests, and the adjustable toe. rest, ar. anged with and applied to the said body, substantially as set heel-rests, and the adjustable toe-rest, arforth. ranged with and applied to it (the said body) 3. The combination of the body-support as specified. plate, its lip, and the recessed base-plate EDWIN J. E. ROLLINS. (arranged and applied as set forth) with the Witnesses: jack-body pivoted to the support-plate, and R. H. EDDY, t provided with the main and auxiliary last, S. N. PIPER.
